I have tried to raise and receive a signal in rtlinux free edition.
the only function i was able to find to send out a signal is kill()
which requires 2 arguments, pid and signal level. however, rtlinux
FREE doesn't really support getpid(), so that the compiler complaints
getpid() is implicit declared. Without correct pid, kill is useless. i
also tried raise(), but it's only implicit declared too.
I'm wondering if there is a right way to do signal in rtlinux. Any
documentation or tutorial on the subject will be appreciated. Thank
